Electricity? They use electricity? No wonder there is nothing on TV.

Yes and no.

Plasma uses more than CFL/LCD (commonly called LCD).
CFL/LCD uses more than LED/LCD (commonly called LED).

Bigger uses more than smaller, within the same design.

Other than that, individual designs vary.

But in general, a large LED uses less than a smaller Plasma.

Indeed. Not sure how true this still is but the peak brightness affects
energy draw. Settings that have brighter highlights draw more power.
Limiting the dynamic range, in what used to be an Energy Saver setting
limited power draw. So, individual designs can very much vary.

Note that the 47" LED LG draws about the same power as the 32" LED
Samsung and a lot less than the 46" LED Sony.

It's complex.

It's the cable box that sucks the power. I don't know why they don't force
that industry into using equipment that uses less power. One cable box uses
about the same amount of electricity as a refrigerator. So if you have more
than one, just think of how much extra you are paying for the stupid box. I
cut my electric bill by $10 a month by using the remote control surge
protector that turns off the power source the cable box when not in use. I
just have to remember to switch it on about 20 minutes before watching
television to give the programming guide time to load up.

Things have changed. My TV set runs Linux, so like a computer, it
actually has to boot up every time I turn it on. The alternative is
having it run all the time, but just in a sleep state.

And so many things now require settings, and if you remove power to them,
such as with a power bar, you then have to fuss with the settings every
time you turn it on. Or, if the thing doesn't have power, you can't turn
it on with a remote. So some of the issue is much fancier equipment than
int he past.

Gee, the blu-ray player I found on the sidewalk at the begnning of July
(no remote, and once I cleaned the lense over the laser, it works) has an
ethernet connection on the back, it doesn't just play blu-ray discs, it's
a computer that needs to be hooked up to the internet to be useful.

That's a big difference from the days when the most expensive electronics
in a household was a tv set, with a big physical channel switch on it.

The surge protector I use has four remote controlled outlets and the rest
are normal. Since my television is LED, it doesn't use much power, so I
plug it into the regular outlets well as the DVD player and Roku. The cable
box is the only one that sucks so much power, so it is the only thing I plug
into a remote controlled outlet so it can easily be turned off and on
without having to reach behind or under the rest of equipment attached to my
television. Since we have three different cable boxes in our home, the
savings was substantial and worth the 10 to 20 minute wait for the
programming guide to load. Even if the cable box is "off" it is still
drawing a large amount of electricity because that programming guide is
constantly reloading. When the outlet it is plugged into is off, it isn't
drawing a bit of power. The point is to avoid paying for electricity 24/7
when the television that cable box is attached to might only be watched for
2 hours a day. Google power usage of cable boxes and you will see what I
mean. It is atrocious.
